چکیده

در این مقاله مسئله چیدمان گیرنده‌ها برای مکان‌یابی غیرفعال در شرایطی که چند منبع وجود داشته باشند و نویز اندازه‌گیری وابسته به فاصله است در نظر گرفته می‌شود. برای این هدف، ابتدا کران کرامر رائو برای مکان‌یابی مبتنی بر زاویه ورود سیگنال، با مدل کردن نویز وابسته به فاصله و وجود چند منبع استخراج می‌شود. سپس چیدمان بهینه‌ای از گیرنده‌ها برای دست‌یابی به کران مورد نظر به‌دست می‌آید.

چکیده [English]

In this paper, we consider the problem of sensor placement for passive source localization under conditions where there are multiple sources and noise measurement is distance dependent. To this end, first we derive the Cramer-Rao bound for the angle of arrival (AOA) based source localization for distance-dependent noise model and existence of multiple sources. Then, the optimal arrangement of sensors to achieve this bound is obtained.
